Standing on the bluffs of Roma, Texas on a May afternoon two border patrol agents look out over the meandering Rio Grande River that separates Mexico from the United States and recall a time when the scene was far less tranquil. Last fall, during the waning months of the Obama administration, hundreds of immigrants crossed the river on rafts at this point each day, many willingly handing themselves over to immigration authorities in hopes of being released into the United States to await court proceedings that would decide their fate. Now, the agents look out on an empty landscape. Foot paths up from the water have started to disappear under growing brush, with only the stray baby shoe or toothbrush serving as reminders of that migrant flood.
